To be honest, I think this panic can wait until this time next week when we've confirmed champs league. If we are to sign a big player then having champions league football is essential.
I personally think Wenger has clocked on that Giroud isn't good enough, Giroud has looked pissed recently, almost as though he knows it's just a matter of time before someone comes in. Defensively it's a must - so I presume that a CB and CDM and the more likely signings.
If Wenger plays Sanchez through the middle upon walcotts return then we shouldn't really have much of a problem (I'm sure Sanchez can put more in than Giroud if he gets the service)
If Wenger buys a striker then it'll be better.. Almost too good to even be true. If we're honest here, Arsene will not want to drop Cazorla so basically, another striker probably wont happen because it will essentially mean that either Sanchez goes left and Cazorla is dropped, or Sanchez rotates with Walcott - and both seem to be a negative.
I'll be fine with Sanchez playing through the middle, he'll do a mad one there TRUST ME. He's already showing glimpses of this. I know people will disagree because for some reason they don't rate Sanchez :/ but if he's played through the centre then all we need is a CDM and a CB.. Considering we have the Ox & Campbell too..
Sanchez
Cazorla Ozil Walcott
Ramsey CDM
Is what we'll likely see I think
